TOOL FOR INSERTING VALVE-STEMS IN PNEUMATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 626,582, dated June 6,1899.

i Application filed June 27, 1898. Serial No. 684,614. (No model.)

To a/ZZ whom it may concern.-

Be it known that l, ALBERT WHIsLER, a cit-izen of the United States,residing at Greentown, in the county of Howard and State of Indiana,have invented a new and useful Tool for Inserting Valve-Stems intoPneumatic Tires, of which the following is a specification.

The object of the present invention is to provide a simple and usefultool or implement for inserting metal stems for inflation-valves or thelike into Vpneumatic tires or other hollow rubber or fiber tubing.

The invention consists, essentially, in providing a holder for thevalve-stem and aplun ger adapted to engage the stem and force the latterinto the opening provided therefor iu the tire.

Other objects and advantages of the device will be hereinafter morefully. described,

shown in the drawin gs, and particularly point# ed out in the claims.

The drawings hereto annexed and the description thereof show and setforth the device as applied in use upon a bicycle-tire; but it will ofcourse be understood that the device is capable of inserting similarparts into elastic tubing of any character.

In the drawings, Figure l is a plan view of my invention applied -to asection of a bicycle-tire and holding a valve-stein in the initialposition for insertion. Fig. 2 is a side elevation showing thevalve-stem inserted in the tire. Fig. 8 is a longitudinal sectional viewof the implement. Fig. 4 is a detail perspective view of the casing andfingers. Fig. 5 is a transverse sectional view on the line ec of Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

Referring to the accompanying drawings, the tool comprises a holderconsisting of a hollow casing l, having fingers 2 and 3, provided at oneend thereof, and a plunger 4c, adapted to be inserted at the otherend ofthe casing. The casing is preferably oblongor elliptical incross-section, so as to provide a convenient hand-grasp for theoperation of the device, and the finger 2 is preferably formed as anintegral portion thereof. The

other fingers 3 are each pivoted to the opposite side of the casing, asat 5, so as to be swung in the. plane of the casing and spread the ngersapart. Each of these fingers is reduced in width, as at 6, for asuitable length of the outer ends thereof, and their extremi ties arebent or formed into outwardlyextend ing flanges 7. The integral finger 2is also formed with such a flange 7. By the disposition of the fingersupon opposite sides of the casing the flanges 7 will extend in oppositedirections upon theinside of the t-ire and serve to hold the devicethereon.

The plunger t comprises a stem 8, having a head or handle 9 provided atone end and a shank l0 at the other end thereof. The stem is of a sizeand shape to fit easily within the casing and be guided therein duringthe operation of the device. The shank preferably tapers toward its end,and a concave notch or seat ll is formed therein. The plunger may beformed of a single piece or, as shown, with the stem S, a hollow tube,and the shank 10, connected to one end, and the handle 9, fitted to theother end thereof. The shank should always be of metal to prevent wearor breakage; but the handle may be of wood or other material, asdesired.

In the operation of the device the valvestem l2 is placed between thefingers, as shown in Fig. 1, its head 13 seated therebetween, with thefinger 2 extending diametrically across the top and the fingers 3 acrossthe under side thereof and embracing the stem, the body of which extendsat approximately right angles thereto. The free ends of the fingers arenow placed in the opening, the reduced portion thereof allowing the sameto come close together for this purpose; The plunger is then'placed inthe casing, with the edge of the head 13 seated within the notch ll inthe end of the shank l0. V'Vith the device thus assembled the casing isgrasped in one hand, with the thumb thereof steadying the valve and withthe other hand pressing upon the Vhandle 9, whereby the plunger forcesthe stem against the tire, thus spreading the fingers 3 apart by reasonof their pivotal connection with the casing and stretching the openingto receive ,the head of the valve-stem. When the valve-stem has beenforced against the tire, a fulcrum-point is obtained at one side of thehead, whereby Vthe latter is turned and forced edgewise into theopeningin the tire by continued pressure f the plunger (See Fig.- ,2)and the valve-.Stem

.assumes its proper position, with its head Within the tire and itsshank protrudingfrom the opening and being received alongside of theshank .of the plunger and between the 4 reduced portions ofl the pivotedfingers 3. 1

The device can then be easily removed by pulling the same from the tire.

. f from the tire until the valve-stein is in place, i

It will be observed that as the valve-stem is forced against the tire it'spreads the piving and prevent the tool from pulling away when the toolmay be easily removed.

A tool constructed in accordance with the present invention will providean exceedingly l simple and useful device for placing Valvef stems andthe like in position without damaging the opening in the tire.

Changes in the form, proportion, and minor details may be made withoutdeparting from the spirit and scope or sacrificing any of the advantagesthereof, and therefore I do not wish to be understood as limiting myselft0 the precise construction and arrangement as herein set forth.

Having thus described the invention, what I claim, and desire to secureby Letters Patenti,
